Application filed January 14, 1916. Serial Bio. 72,090.-

To all whom it may concern:

residing at 610 Berri street, Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Heaters; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in a heater for supplying hot water and the object of the invention is to devise a heater of simple construction, economical in the use of the steam and especially simple of construction.

The invention consists of a casing through which cold water enters at one end and'the hot water comes out through the other end, which is provided with a dome at the upper end and one at the lower end and a plurality of tubes connecting said domes together,

means to connect the tubes to the lower dome, a condensation water pipe secured to the lowermost dome leading outside through the water inlet, the upper dome being fed by steam at its upper end.

The invention will be better understood with the aid of the accompanying drawings, in which Figure 1 is a vertical section through the heater according to the invention, while Fig. 2 is a vertical sectional view of the connecting means of the tube.

Like numerals of reference indicate corresponding parts in each figure. y

In the drawings, 1 is the casing of cylindrical shape and supported in a vertical position on the base 2 which is detachably secured to the lower end of the casing bythe bolts 3.

The heater is provided with a water inlet 4 at its lower end in the base 2, and a water outlet 5 at its upper end in the casing 1 andth a packing gland 6 at the upper end around an orifice 7 leading through its wall.

8 is a dome disposed withinthe uppermost part of the casing 1 provided at its upper end with a tubular extension 9 passing watertight through the gland 6, said tubular extension having an inwardly projecting portion 10 provided with a number of holes ll for the escape of steam into the dome.

14 is a lower dome fitting within the base portion 2 and inverted in relation to the upper dome, said dome comprises a plate 15 provided with perforations 16 adapted to receive the lower ends of the tubes 13, the outer edge 17 of the plate being secured v by the bolts 3. 17 are a plurality of holes in said plate 15 adjacent to its outer circumference for the purpose of permitting the water entering iilllfmllgll the inlet 4 to pass pipe connected at the lowermost part of the dome 14and projecting through the water inlet 4. In order to secure the tubes 13 to'the plate 15, the tubes are threaded at their lower ends to engage the corresponding thread in the nipple 24, said nipple 24 being provided with a nut head which naturally rests against the lower side of the plate 15, on gaging, at the same time, the corresponding thread in the perforations 16 in said plate, thus rigidly securing the lower ends of the tubes 13 to the plate 15.

- It will be observed that of the tubes 13 at their will be. considerably reduced, and this will cause the steam engaged in said tubes 13 to be slightly checked.

It may be stated that the upper dome 8 is normally disposed a little below the upper the inner diameter extreme lower ends end of the casing 1 in order that when the steam enters thevdome the latter may exd, during which time the tubular extension 9 may slide in the gland 6. p

In the operation of the invention, the

tubular extension 9 is steam supply andthe steam is admitted to e upper dome, to pass downwardly through the tubes 13 and into the lower dome 14 in which it condenses, the condensation water dripping through the condensation water pipe 20. v

I wish it to-be understood that the details of construction herein set forth and shown in the drawings, are but one suitable arrangement and may be somewhat modified if found desirable, so long as the essential features are retained as set forth in the following claims for novelty.

at I claim is:

1. A heater of the character described comprising a casing and a base, a water connected up to the casing, a

inlet in said base and a water outlet in said dome in the upper part of said dome in the base, tubes secured to said upper dome, means to secure said tubes to the lower dome, a condensation waters pipe connected to the lower part of said dome and projecting through the water inlet, and means to supply steam in said upper dome substantially as described.

2. A heater of the character described comprising a casing and a base, a water inlet in saidbase and a water outlet in said casing, a dome in the upper part of sai casing, a dome in the base, tuoes secured at one end of said upper dome, means to secure the lower ends of said tubes to the lower dome, said means compressing a lung for their lower inner ends, which rdiameter, a condensation water pipenected to the lower part of said lows: leading through the water inlet, a to supply steam through the top of u; per dome substantially as described.

3. A heater of the character described comprising a casing and abuse, a water.

inlet in said base and a water outlet in said casing, a

tween the lower end of the casing and casing, a dome in the uppermost part of with a plurality of bethe base, the said plate being provided with a plurality of threaded perforations and with holes through its outer circumference; a lower dome suitably secured to the under side of said plate; tubes threaded at their upper ends in the perforations of tie mpper dome, said tubes being provided with an inner thread, their lower ends resting on said plate above said threaded perforations; a nipple provided with an expanded head and threaded on its outer side and engaging the threads in said perforations and tubes; a condensation water pipe secured to the lower part of said lower dome leading provided the said casing a plate secured threaded perforations;

through the water inlet outside of the base,

substantially as described. Signed at Montreal, Quebec, QQth-day of November, 191
